Abstract

The lens effect of pressure windows has been studied at pressures as high as 30,000 atmospheres. These lens effects are found to be due to four primary causes. 1st. Pseudo lens effect caused by temperature gradients in the material under pressure. 2nd. The bulging of the outside surface of the pressure windows. 3rd. The Pseudo lens effect due to unequal strains in the glass. 4th. The bulging of the inside surface of the window combined with the difference of index refraction of the material under pressure and the glass or quartz of the window. Methods for correcting for these lens effects are outlined.
